From future to nowadays, water management under strain

Climate change will alter water availability. The way to adapt can be examined in the light of current situations where water scarcity already exists. This is the case of Tille's watershed in which a planification of withdrawable volumes has been engaged, to avoid drought's water restrictions. We show that instruments dedicated to quantitative management improve knowledge on resource, but don't trigger changes in water uses. The technical expertise and the handling of the issue in a deliberation manner do not open enough discussion to address possible futures.
